stall Patent No. 1,3- MQ'ZG there is described a' double-sided combing` machine of this type, wherein there lare two combing eyt indcrs mounted side by' side,l each (o-operating with the nipper mechanisms on its side of the machine, these nipper "reines being mounted in two 'roc-is parallel with the cylinders and back to back Ato be operated alternately by a swingi g' arm or pendulum `so that the nipper irameson each sident' the machine are all periioimingg` the same duty at the same tin e, the nippers on one side of the machine being open while those on the other side are closed. My pres ont invention comprises a new mechani" L for' thusoperatii 5' the nipper frames wh ch is cqnaiiy applicable 'tor use in connection with the double-sided combing machine. as` shown in said Tunstall patent and with a sine' -sided machine. lv have described my invention particularlv in connection with a double-sided machine,` like the 'llunst but do not limit it to such a machine7 is applicable to other woll in it and also causes the operation of 'the' top-combs which are connected with it. invention, however, lends itsell to use in :i singg'lessideil comber, that is a comb-er in which :i single rock shaft only with its nipper trames, etc., is 4used-as will be readily Linders cod.

iii my piwcni invcinion imc roedenVL .fifi it' lnown combing Y imichmes Y1-'ill appear to those skilled 1n ts are provided on pinion on shaft l like the the `number of employed aniihavc described in' eliminated some the Tunstall machine "a i. trier ways simpliiied thedesigf ofthe machine while maintaining' all of itsinany goed points.

ln' the drawings .ll have shown in connection with mk vinvention means for operating; them scribed Vin .the Tunstall application, Serial No. G'YLLTOQ. filed November 14 1 f3, latent No. 1,535,701, April 28, 1925, wif-'h the ci:w ception that `in this appiication the top comb receives power directly from the saine pari; as the nipper `frames being,V tiedV to the rock 'lop combs and' such as is '-e-f shaft on which the nipper tram-es are monnted. Other top comb inechanismmay be used or the top comb mechanism may be otherwise operated 1f desired.

My invention will be understood by refer ence to the drawings in which it is shown in its rpreferred form.

Figure l. is' an end elevation showing 'the vpreferred construction for operating the rnipper framesin either a single or 'doubie sided comber.

Figs. 2, 3 and fi are sections on lines Q-f) 33-8 and l-4, respectively, of Figli?, these7 vis views being` taken'looking'in the direction of c the `arrow in each case.

Fig. 5 `1s a side elevation of the end oi1 the machine which carries the-gearing, etc.,

by which motion is given to the heads,` andl also a'portion of Vone of the heads, and

F 1g'. 6 is va ligure corresponding to Fig'.

1, showingmoditication of the mechanism of Fig. l, the sprocket wheel, for driving thek cylinder' brushes, however, being' removed.

For purposes of identification oi the loca-- tion of some ofthe corresponding `parts in the said Tunstall patent and application. some of the parts are given the same reference numbers as inthe said patent yand application. 'il isa base and A2, A3,' fr* and A5 are Jframes Ato support the shafts, etc.'

, l is the power shaft which carries 'a fly wheel 2 and pulley (not shown). 'is a pinion 3 in the said Tunstall patent.

63, 63 are two shafts, each carryingf` combing cylinders (not shown) to oo-opera'te with vthe nipper frames -on the vtwo sides oi" the machine as in the said patent. 'One ot,

these shafts carries the zgear 651 in mesh with the pinion 3 and each shaft carries a gear 65() which gears are in mesh (see Figi. 2) so that the shafts 63 are rotated in opposite directions.

In mesh with the gears 650 are idler gears 113 which are in mesh with gears 114 on shafts a. carrying a crank disk 1141 in the Tunstall Patent No. 1,394,054)-to operate the clutch mechanism by which the detaching rolls are operated. The clutch b is mounted on shaft 921, beine; the crank pin on the crank disk 1141 by which the throw ot' the link l115 operatinp` said clutch mechanism is caused as in said patent.

In the said Tunstall Pat-ent No. 1,351,076 each nipper trame is hung to swing` on a stationary shaft 29 mounted in .trames A3, A4, A5, etc., the movement being` given to the nipper frames by means oi a sii/inging lever 12 mounted on a stud 18 (see Figs. 3, 7, 8 and 15 of said patent). My present invention includes the elimination ot the parts shown in Fig'. 15 ot said patent and the mountingr ot one shaft 29 on each side of the machine in such a manner that each will be rocked and carry with it the nipper 'trames which are keyed thereto and, in order that they may be rocked positively, l have ex:- tended downward from each` arms 10 t see Figs. 1, 5 and G) which are also keyed to the shafts 29. each arm being` adjustably connected with a lever 12 tulcrumed on'a stud 13 carried by the frame A2, and each. carrying near its lower end a bowl 14am)` at its extreme end a pin 15 to which is at tached a spring` by which its bowl is kept in contact with cam 16 mounted on the shaft 8. As shown one end oteach spring- 150 carries a. hook 151 to engage the pin 15 and the other end a rod 152 which passes through a bracket 17 on the lower end ot the frame A2 and is held therein by nuts 1S.

The cam 16 is suitably shaped. to give the desired movements to the nipper frames and the top comb mechanism attached to shafts 29. ln Fig. 1 the bowls 14 are engaging opposite surfaces ot the cani. The cam surtace, as shown on the right, has the largest radius and has a trueradius through an arc of a su'tlicient length to permit the nipper frames and top combs to remain stationary while the cylinder needles are combing; the tufts held by the nipper trames. To place the nippers in this position, the portion ot the cam having the largest and true radius has thrown the lower end of the lever 12 outward against the pull of the spring' 150,

thus rocking its arm 10 to the lett and turn-V ing the shaft 29, so that it has thrown its nipper trames to the left, that is, into closed position. The nipper trames thus nip the tufts to be combed, and remain stationary'. while the largest and true radius ot the cam is in contact with the bowl 14. The cam surtace, as shown on the lett, and those portiens ot the cam surface joining the lett hand portion with the true radial portion shown on the right, are so shaped as to allow the spring 150 to pull the lower end of the lett hand lever l2 to the right, thus rockingV its arm 10 to the lett and turning` the shaft 29, so that it will throw its nipper frames mounted thereon and top combs connected therewith outward with the nippers open, and also so shajed as to lrive the nipper trames and top combs an appropriate reciprocating movement. so that they may co-operate with the detaching rollers in detachinn` and piecing up the fleece.

rThe opening); and closing` ot the upper nipper upon the nipper plate will be understood more particularly troni Fig. 4 in which the lower nipper is marked 19 and the upper nipper 20. ln the arms or side plates 28 ot' each nipper 'trame is mounted a shatt 21 which carries arms 22 on which the upper nipper 2O is tixedly mounted, this construction beinp; such that the upper nipper is free to be given an oscillating,` movement. On the upper side o't the arms 22 is mounted a plate 24 preferably ot hardened steel. From the top of each trame are hung brackets one on each side thereot corresponding' to the similar brackets 45 in the Tunstall patent, but diiterently shaped therefrom because by my invention l am able to do away with shait l?) of said Tunstall patent. ln the lower end oi two opposing' brackets are adjustably mounted two levers 25 each ot which carries at one end a bowl 2G adapted to rest upon one of the plates 24.y the other end ot each lever being attached to a spring' 45, the other ends ot these springs being' attached to a convenient portion ot the trarne. The tendency ot each ot these springs is to pull upward that end ot the lever to which it is attached and hold the bowls 26 against the plates It will be seen from this description that upon the inward movement ot one ot the nipper trames, say that on thel right ot Fig. the plate 24 will push against the rolls 2G and the corresponding upper nipper will be closerl against the lower nipper by a. yieidinpl pi.e.-fsure as in said patent. rlhe upper nipper is returned to open position by an arm 4l mounted on the end ot the shaft 21 and a cam surface 42 on the frames as shown in said patent which engage when the frames are drawn into forwa d position as shown at the left oit Fig. 4.

It will be seen trom Fig: El `that on these same shatts 29 are also keyed arms 32, a pair to each head or unit, which correspond to arms sin'iilarly numbered in said rlunstall application. To these arms, as shown, is attached a top comb 48 as in said application. Each shaft 29 thus causes the top comb to be oscillated at the same time that the nipper frame is oscillated. Hence the nipper frames and the top combs on each side `of the machine are caused to operate as a single structure and the swing of the `top combs and the nipper frames may be adjusted by the one adjustment of the shaft operating mechanism and that adjustment may be caused in the following way: Referring to Fig. 1, it will be noted that the arms 10 are each slotted near its lower end as at 11 and in the slet is mounted a block 2S which capable of sliding' therein. A. screw 30 passes through a lug 331 onv the upper end of the lever 12 and `through a swivel 31 mounted in the bloclr 28, this vscrew being provided with suitable set nuts. The rotation lof the screw 3 will change the location of the bloclr 28 inthe slot 11 .and hence will change the location of the connecting point or -pivot between the rocker arm 10 and the lever 12 so that the radius of swing of the arm 10 may be adjusted.

his same result may be secured by the modification shown in Fig. 6 where the lower end of the arm 10 is connected by a link 321 with the slotted end 33 of the straight lever 121 to which it is clamped by a screw block and clamp nut 34, an adjusting screw 35 being provided, as in Fig. 1. by which the position of the end of the link 32 may be adjusted with relation tothe upper end of the lever 121 when the clamp nut 34 is loosened.

For this purpose the upper end of the lever 121 is provided with a lug 36 through which the screw 35 passes and nuts 37 are also provided by which this adjustment may be made and the parts thereafter set. As shown, the

upper end of the lever 121 is thickened for strength.

It will be noted that the use of a cam 16 andsprings 15.0 for the purpose of throwing the nipper frames enables the nipper frames to be given their desired movements positively such that each nipper 'frame may have an active forward movement and may also be held stationary `while the combing cylinder is passing through the tuft, which is a very desirable feature as it allows the combling cylinder to perform its function with certainty and thoroughness. It allows it also to be given an appropriate movement to malte it co-operate to the best advantage with the det-aching rolls.

While it is undesirable in machines of this character that cams as a general rule should be used, the cani in this case given such light work and is of such size. that its wear will be negligible and this wear, if there be any, will not have the tendency to force the nippel-s into the combing' needles. The upper nipper is yielding because of the use of the levers 25 and springs 40 as in the Tunstall comber,

It wil-l of course be clear to anyone skilled Viary means with the brushes for cleaning the combing cylinders.

In Fig. 3 there are shown `pinions 89 and 891 each of which is fixed on the end `of a lower detaching roll and which are connected the idler 907011 stud 91. Pinion 89 vengages the `gea-r 92 on the clutch l) yon shaft 921 so that the clutch I), operated as `in said patents, drivespinion 89 which in turn drives the idler 90 and the pinion S91. The

shaft'S also carries a disk 105 which isat-tached to rocker arms 108 by slotted adj ustable connections 109, these rocker arms 108 being attached to shafts 103 which are con` neeted to the detaching roll motion as shown in Figs. 6 and 12101:' the said Tunstall patent.

The operation ofthe top `comb being fully desc 'ibed in the said application, it is not described here except to say for identification (see Figs. 3 and 4) that 140 is: a link one end of which is connected to the rocker arm 32 and the other is connected to the linlr 141 free to swing on shaft 142, but adjustably attached thereto `by means of the vplate 144 and the adjusting screwsv 146. The link 141 is fiXedly attached to the shaft 142 and to it is adjustably connected the arm 153. This mechanism is duplicated on the other side of the head and between the arms 153 the top comb 4:3 is mounted so'that the top comb will be reciprocated horizontally, the free arm 152 resting on the friction roll 156.

In Fig. 2 it will be noted that the gears 7 and 114e are slotted and show bolts c pass ing through the slots. For adjustment each shaft a and 8 has a disk eiland 81 fiXedly attached thereto. The gears are attached to these disks by the bolts c. rrlllhus the posi'- tion of the gears on the shafts may be adjusted.

It will be seen that while as shown in the drawings the nipper frames on both sides of the machine are operated alternately, the cam may operate either one v.of the sides alone as the nipper fra-ine and top comb mechanisms are entirely independent ef each other. Hence, as will be clear, my improvement is not essentially upon a. double-sided comber, but comprises a nipperfoperating mechanism which may be duplica-ted for use in a double-sided machine, for example in the way above Vdescribed and operated by a single cam or the like. lf the machine is built as a single-sided machine, the nipper frame and top comb may equally wellbe operated without change. Y

adjust Sil fil

In any case the nipper frame always comes back to the same point over the combing cylinder, this point being controlled by the shape of the cam surface. It must be re- '.nembered that the fibres on which the .nipper .frames act are very minute in character and a very slight change in the inward throw of the nipper f ame will vary the relation of the nippers to the combing cylinder, which would result in imperfect combing.

IVhile I have described my invention as used in aparticular structure, which is the iest form thereof now known to me, I do not n'iea'n to limit myself to the details shown as it me" be embodied in other forms as rwill clearly appear to those skilledin the art.
